Structural Features
Dual-suction impeller design: The impeller consists of two back-to-back impellers combined together, allowing liquid to be drawn in simultaneously from both sides before converging into the volute casing and being discharged. This unique design doubles the flow rate—compared to a single-suction pump—at the same impeller diameter, while the symmetrical arrangement of the blades effectively balances axial forces, reducing bearing wear and ensuring smoother operation.
Horizontally split pump casing: The pump body is horizontally divided into upper and lower halves along the axial line, allowing maintenance without dismantling the pipelines—simply lift off the pump cover to access and service components like the impeller and sealing rings, significantly reducing both maintenance costs and time.
Volute Flow Channel Optimization: The spiral volute design ensures smooth liquid flow, minimizing turbulence losses and enhancing hydraulic efficiency. Some models feature a coating made from advanced polymer composite materials, which further reduces frictional resistance, boosting efficiency by an additional 2% to 5%.Performance advantages
High Flow Rate and High Head: The flow range covers 82–2020 m³/h, with head capabilities spanning 13–125 m, making it ideal for long-distance and large-area transportation applications—such as inter-basin water diversion and agricultural irrigation.
Excellent cavitation resistance: The double-suction design ensures uniform inlet pressure distribution, and when combined with the optimized impeller inlet shape, it effectively reduces the Net Positive Suction Head (NPSH), thereby extending the pump's service life. For instance, the SH-type double-suction pump demonstrates a 30% reduction in NPSH compared to single-suction pumps when handling 80°C clear water.
Adapting to Complex Operating Conditions
Media compatibility: Capable of handling clean water, wastewater, chemical liquids, and media containing solid particles (such as silt or sand). By selecting corrosion-resistant materials like stainless steel and fluoroplastics, it meets the requirements of various media types.
Temperature Range: Standard models can withstand temperatures up to 100°C, while high-temperature models (such as those used in boiler feedwater pumps) are capable of handling media exceeding 200°C.
Pressure Resistance: The system can handle working pressures up to 2.5 MPa, making it suitable for high-pressure delivery applications.Low vibration and noise
The symmetrical structure balances radial forces, ensuring even bearing loads and keeping operational vibration levels below 2.8 mm/s, while noise remains at or below 85 dB—meeting stringent industrial environmental standards.
